Question

Arrange the following layers of atmosphere starting from earth's surface.
A. Troposphere
B. Stratosphere
C. Tropopause
D. Stratopause
E. Mesosphere

• A. A, B, C, D, E
• B. A, D, B, C, E
• C. A, C, B, D, E
• D. A, C, B, E, D

Hint:

A mnemonic for the layers is "Trust Me in The Exam": Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere. The 'pauses' are the ceilings of the layers below them (e.g., Tropopause is the top of the Troposphere).

Answer 1

The Correct Option is C

Step 1: Identify the main atmospheric layers.
The atmosphere is divided into layers based on temperature profiles. The main layers from the ground up are the Troposphere, Stratosphere, Mesosphere, and Thermosphere.

Step 2: Identify the boundary regions ('pauses').
The 'pauses' are the boundaries that separate the main layers. The tropopause separates the troposphere and stratosphere. The stratopause separates the stratosphere and mesosphere.

Step 3: Construct the sequence from the Earth's surface upwards. 1. Troposphere (A): The lowest layer, where we live and weather occurs. 2. Tropopause (C): The boundary at the top of the troposphere. 3. Stratosphere (B): The layer above the troposphere, containing the ozone layer. 4. Stratopause (D): The boundary at the top of the stratosphere. 5. Mesosphere (E): The layer above the stratosphere. Conclusion: The correct order from the surface up is A, C, B, D, E.
